Preventive Maintenance
Maintenance on the unit is simplified with the following
preventive suggestions:
Filter maintenance must be performed to assure proper
operation of the equipment. Filters should be inspected at
least every three months, and replaced when it is evident
they are dirty. Filter sizing is shown in
Table 57, p. 59
:
Check the contactors and relays within the control panel at
least once a year. It is good practice to check the tightness
of the various wiring connections within the control panel.
A strainer (60 mesh or greater) must be used on an open
loop system to keep debris from entering the unit heat
exchanger and to ensure a clean system.
For units on well water, it is important to check the
cleanliness of the water-to-refrigerant heat exchanger.
Should it become contaminated with dirt and scaling as a
result of bad water, the heat exchanger will have to be back
flushed and cleaned with a chemical that will remove the
scale.This service should be performed by an experienced
service person.
Condensate Trap
For units incorporating a negative trap design, ensure that
the condensate system is primed with water at all times.
Allowing a negative, pressure condensate system to run
dry could cause a break in the condensate seal allowing
the fan to draw water from the condensate line to spray
moisture into the mechanical system. By maintaining a
primed condensate trap, a seal will be created and will
help prevent these complications. The condensate trap
must be field installed.
Note:
When maintenance is performed on this unit, care
should be taken not to damage the foil face
insulation surfaces. If damage occurs repair
damage with foil faced tape.

WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
NOTICE
Proper Water Treatment Required!
The use of untreated or improperly treated water in
coils could result in scaling, erosion, corrosion, algae or
slime. It is recommended that the services of a
qualified water treatment specialist be engaged to
determine what water treatment, if any, is required.
Trane assumes no responsibility for equipment failures
which result from untreated or improperly treated
water or saline or brackish water.
